Tracking simulations


12 July 2009

Files "tst_sizeStudy_pions..." contain x-y intensity distributions of pions at the z-positions of the last double layer of each tracking station DC1,..,6 (z= 3125 mm, 3445 mm, 4245 mm, 4685 mm, 6225 mm, 7675 mm). The distributions were obtained by Ola Wronska in MC simulations of pion tracks with monoenergetic pions generated uniformly in the phi and theta angle at the target point and passing through the area x=+-551 mm, y=+-273 mm at z=3125 mm corresponding to the nominal angular acceptance of the Forward Spectrometer (+-10 deg. horizontally and +-5 deg. vertically). The energy losses as well as multiple scattering on the beam pipe and the detector structures was included. The simulations were performed for the magnetic field in the PANDA solenoid equal to 2 T and for two settings of the dipole magnet corresponding to the beam momentum equal to 7.8 GeV/c and 15 GeV/c. For each beam momentum setting, intensity distributions of pions with momenta equal to 2%, 5%, 8%, 10%, 20%, 50% and 70% of the beam momentum were determined.
